If you’re new to fly fishing, you might not yet know the name John Barr. Chances are, you have some of his patterns in your fly box already. Barr’s Flashback Emerger is one of those patterns that has a home in any fly box — any time there is a mayfly hatch and those pesky trout won’t seem to eat your dry fly, change it up and fish the Flashback Emerger in the surface film and you might just have a killer day!
